Where do I order SImpsons personal checks?

In a subplot, when prodded to get away from the television and get some exercise, Bart offers to learn karate, only to skip out of each lesson in order to play in the mall arcade. Whenever he is questioned about the techniques he has learned, he refers to the "Touch of Death", an ability seen in one of the arcade games he plays. His actions catch up to him when Lisa prods him to defend her and reclaim her saxophone.
